Really Weird Dream About Anxiety

Ok, I’m sorry for writing about a dream than direct anxiety, but this is scaring me very much so I need somebody to explain this to me, and to tell me I’m fine.
So the dream just begins with me feeling extremely weird and breathing hard and just feeling “off” in general. [KEEP IN NOTE: I was weirdly calm the entire time this nightmare was happening, and while I woke up too.] So basically I felt like I was just in one room and then the next, and it was just so weird. There was no space in between, I was just in one place and then the other. At one point, I remember appearing in the bathroom in front of the mirror trying to finish putting my clothes on. My shirt was rolled down so I had to pull it up to cover my stomach, but gravity. And I had to zip and button my jeans, but it was to the side of my hip. It was just so strange. At the end of the dream, I remember sitting down on my bed trying to breathe slowly, and realizing that I should have yelled for help when I could have, because as I was breathing slower and slower, the room started shaking around in my vision and going in circles. I then layed down on my bed trying to breathe slowly but the spinning just got worse and my ears started ringing loudly. It wasn’t suddenly, but I feel like maybe 5 seconds after I knew I passed out, I woke up, but it just felt like a transition. It’s hard to explain but it didn’t feel like I woke up, it just felt like I got back up from passing out in my dream.
Anyway, what scares me a lot is that sometimes I’m scared to tell people that I think I’m scared something is wrong with me, or that I’m scared I’m going to die, which explains why I regretted not telling my dad before I could no longer control my fate, and now I feel like i am going to die.
For the past few days, school has just started, and I’ve been acting kind of weird. I haven’t been able to focus, and I just feel sort of detached from everything. I’m super awkward around people, and when I’m texting people, I just really don’t know what to say. It’s like I’ve forgotten how to act Normal.
Please just help me decipher this dream, and help me believe that I will be ok.
Btw, I’m sorry if I’m not consistently active in this post because, life.
